Rihanna is feeling blue!

The singer rocked some cool blue lipstick at her Rihanna for River Island Spring/Summer 2014 collection launch in London on Tuesday. And wow, did she turn up the electricity! We knew RiRi was a fan of the eye-catching trend, after we spotlighted blue lipstick in a beauty how-to. We have to say that Rihanna sure pulls off the fierce hue with such confidence and strength. 

The cropped-cut songbird went with a toned down matte shade, which is great for a day or casual look. The Bajan beauty paired the bold lipstick with a pretty dark and simple look.

Rihanna wore a black mesh top covered by a varsity jacket, and a pair of fitted blue jeans. Nice move, Ri! No need to overshadow the blue power; just let your lips make a statement all by themselves.

Being such the daring diva, RiRi must have used lip liner to define her pout. Yes, ladies, rocking Smurf blue takes a little bit of work, but Rihanna gets it right.
